I found a tome pedestal with an exclamation mark over it on the map, and an NPC standing by it trying to read it, in one of the Cathdral levels. The NPC warns you to stay away, but if you activate the pedestal, he turns into a unique monster. Have not seen him in previous beta versions, and only encountered him twice in this one.
I just found a little box object on the ground next to the blacksmith in town, containing a letter from the blacksmith's wife to him. Maybe I was just unobservant and have not seen it before, or maybe you only see it if you've completed his quest in the same game.
